Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2. Introduction
• The metabolic effects of the different systems of the body:
– controlled by autonomic nervous system and the
secretions of the endocrine, or ductless glands.
• Hormones:
– heterogeneous group of chemicals,
– released into the blood stream and travel to all parts of the
body.
• The pharmacology of the individual hormones is of
importance,
– under or over production of the hormones can have
striking metabolic consequences.
2
3. Introduction cont…
• The hypothalamus and pituitary gland function
cooperatively as master regulators of the endocrine
system.
– control reproduction, growth, lactation, thyroid and
adrenal gland physiology, and water homeostasis.
• Deficiency or overproduction of these hormones disrupts
this control.
• Clinical use of protein hormones in the past was limited;
– Preparations had to come from glands or urine.
• Recombinant DNA techniques and the development of
more stable analogues that can be injected in a depot form
– permit increased and more effective use of these
hormones.

5. Uterine Stimulants/ Oxytocics
1. Oxytocin
• Is a cyclic 9–amino acid peptide
• Synthesized in the paraventricular nucleus of the
hypothalamus
• Transported to the posterior pituitary for storage.
• Its mechanism of action
– direct stimulation of oxytocin receptors found
on the myometrial cells.
• Contract uterine smooth muscle.
5
6. • Also causes contraction of myoepithelial
cells surrounding mammary alveoli,
–leads to milk ejection.
• Circulates unbound in the plasma.
• half-life of approximately 5-15 minutes.
• primarily inactivated in the kidneys and
liver.
7. Oxytocin cont…
• Generally considered to be the drug of choice for
inducing labor at term.
• Successful in inducing and augmenting labor.
– In patients with labor disorders.
• Used following incomplete abortion (retention of parts of
the products of conception).
• may be used after full-term delivery to prevent or control
uterine hemorrhage.
• Oxytocin in high doses is used to induce abortion.
• Inappropriate use of oxytocin can lead to;
– uterine rupture,
– possibly maternal death.
7
8. Oxytocin cont…
• Prolonged stimulation of uterine
contractions can result in the following fetal
adverse reactions:
–persistent uteroplacental insufficiency,
–sinus bradycardia, premature ventricular
contractions, other arrhythmias, and
–fetal death.
8
9. Dosing;
• Induction of labor,
– initial infusion rate of 0.5–2 mU/min is increased
every 30–60 min (max. infusion rate is 20 mU/min).
• Postpartum uterine bleeding,
– 10–40 units are added to 1 L of 5% dextrose, titrate
infusion rate to control uterine atony.
– Alternatively, 10 units of oxytocin can be
administered by IM after delivery of the placenta.
10. 2. Ergometrine
• Ergot (Claviceps purpurea) is a fungus that
grows on rye.
–contains a surprising variety of
pharmacologically active substances
(Ergot alkaloids).
• In 1935, ergometrine,
–isolated and was recognised as the
oxytocic principle in ergot.
10
11. Pharmacological actions:
• Ergometrine contracts the human uterus.
• Ergometrine also has a moderate degree
of vasoconstrictor action per se.
–reduce bleeding from the placental bed
(the raw surface from which the
placenta has detached).
12. Ergometrine cont…
• Can be given orally, IM or IV.
• Has a very rapid onset of action and its effect lasts for 3-6
hours.
• Unwanted effects:
– Vasoconstriction with an increase in blood pressure
associated with nausea, blurred vision and headache can
occur,
– vasospasm of the coronary arteries resulting in angina.
Dosing:
• Prevention and treatment of postpartum haemorrhage,
– IM injection: 200 mcg immediately after birth.
• Excessive uterine bleeding: Slow IV injection: 250-500 mcg
immediately after birth.
